Its the geometric symbol for congruent too , and not in open office function editor, which calls the equivalance symbol congruent .

The best stop gap solution would be to screen shot your formula and edit in a photoshop type editor.

I use gimp which is a free editor and just as powerful .

If you then search Google images for ' congruent symbol ' you can copy the one you prefer to your clipboard and paste it in.

There are a lot of formula editors on the market all have limitations but you are using the best of the bunch I think.

]]>I have noticed that there are some symbols that are used in Modern (abstract) Algebra, that aren't necessarily listed in the math reference. "oplus", indicating a direct product between 2 groups, is one such example. I would like to track down a few others.

My most pressing need, is the sign for "is isomorphic to". (a tilde above an equal sign) How do I make this?

Please help.

I didn't find the right solution from the Internet.
